MACHINE FOR ROLLING BIM EDGES.

ApplicationI led January 13,1920. Serial No. 352,572.

This invention relates generally to rim vrolling machines and more particularly to a' machine for finishing the edges of clincher rims. It is well known that theclincher rim is made from a strip of sheet metal which is first rolled into circular form, welded,` and then rolled into'tinal form by rolling over the edges of the band giving the rim as a whole the proper cross sectional IU contour, and inasmuch as the edges of the uclincher rim come in contact with the tire p shoe, it is of the utmost importance that these edges should be rounded and smooth instead of sharp or angular in order to prevent wearing of the shoe, and .it is Vwith the idea'of not only rounding the edges but also somewhat enlarging' this rounded edge that the present machine has been designed, the resultant rim having an edge which, as before stated, is not only rounded but.slightly enlarged providing a contacting edge superior to the edge heretofore provided upon clincher rims. With these objects in view, the invention consists in the novel features of construction and in the manner of com'- bining or arranging the various parts,` all of which will be more fully' described hereinafter and set forth in the appended claims.

In the drawing forming a part of this specification, Fig. 1 isa side lelevation of a lmachine embodying one form-of the invention; Fig. 2 is an 7end elevation partly in section; Fig. 3 is a top plan view; Fig. 4 is view ofthe shaping rolls.

In the practical embodiment of four inven f the said machine; and Fig. 5 is an enlarged tion, we employ a shaft 10 the rear Aend ofV which is' mounted in a suitable bearing 11 V and the forward end thereof in a suitable v ings 11, and in practice lwe prefer to make the gear 16 twice the size of the gear 15 so that whatever the speed of the shaft 10 may be, the speed Vof the shaft 17 will be one-'half .'-'thereoandinordinarypractieatheshaft a sectional elevation of a rim nished upon' ried by a shaft 17 journaled also 1n the `bear- 10 is driven about five hundred revolutions per minute thereby moving the shaft 17 two elevated vertically when desired. vThe for.'

ward portion of the shaft 18 is journaled in a bearing 20 ,which is movable vertically upward in its frame by means of the rods 21, j

crossv head 22 and piston 23 vworkin in the cylinder 24 which -is part of the ousing 25, and the downward movement of the bearing with its shaft is accomplished by thle. iston 26 working in the cylinder 27 wnc pressure being applied to the cylinders 24 and 27 through the pipes 28 and 29, respec tively. 1 x

A shaping roll 30 is rigidly mounted upon the forward end'of the shaft 1() and is adapted, tov -tinto the rolled over edg of the clincher rim, A31, and a shaping roll 32` is rigidly mounted upon the forward end of the shaft 18 and is adapted to engage' the outer side of the clincher rim as most clearly shown in Fig. 1, and a table 33 is connected to the frame at 34 and provides a horizontal support for the clincher rim during the period that its edges are' being operated upon .by the shaping rolls'. 4 The shapin roll 30 has a conical portion 30'* and a hea or knob 30" which is of such size and sha e as to fit snugly within the rolled over 4e ge of the clincher rim, and between the cone portion 30 and the headl 30" there is an intervening groove portion 30.* into which the edgeo the rim is adapted to fit. The' shaping roll 32 has a cone portion 32.* which corresponds with thecone portion 3'0 of the shapingvrpll 30 and it also 'has aY grooved portion v32"- which is shaped .to receive the exterior of the rolledover side of the clincher tire and the f cylindrical portion 32 extends inwardly 'suiiciently to rovide a 'suitable lbearing point for the si e of the tire while the head` 3.0 is in en gement with the rolled over edge of the tlre, and it will l.be noted that the grooved portion 30 is exactl eoextensive Jwith the maximum depth of t eentire rim,

' that 'is the rear ecfge of the groovedv rtion isin directverti y alignment with t e rear ed ofthe ved intermediate portion.

is a part of the housing, through a loo operation, the :roll 321i; elevated and .ne r

arim 31is placed upon the table with itsV edge over the head 30b of thel shaping roll 30 and then by' the application of fluid pressure the roll 32o is'brought down until its conical portion contacts with the conical portion of the'lower `shaping rollend in the `.swelling or enlargement, therebygreatly im roving4 the edge of the meantime the rim 'has been traveling around upon the -table and between the rolls and the-rolls being held in contact with each other, the actual edge. of the rim is forced l` into the intermediate grooved portion 30 and is=there mot only rounded butl given a. slight sis-'indicated at '31,

rim. ter one' e` ge of the'rim has been finished, the upV er iinishingrol-lis-"elevated,

the rim remove and reversed 'andthe 'other edge .finished/as previously described.

The table 33 is adjustable within 'certain limitsin' order to maintain -the rim in its exact proper position, and -also to accommodate diferentlwidths of rims. By .having the shaft 17. mounted in Afixed bearings and. 'providing a universal coupling 19 between the parts 17 and V18a vastly stronger 'and more durable machine is provided.V

By the mechanism 'herein shown vand described, it is possible "to quickly refinish the; of a clincher rim', such. finishing not' ed on y eecting the rounding fo'f said edges ibut also perceptibly enlarging .or swelling l said edges whereby an -improvedclincher rim is rovded.

Having thus described our invention, what g the first named ear whereby sai LLammel -4 the combination with a shaft havingr a shaping roll uponjits forward end and a gear upon the rear portion of said shaft, a second shaft comprising affront section and a rear section connected `together by a 'universal joint so as to permit the axial insertion and removal -of the rim between the rolls, the 'rear section having a gear meshing with the gear upon the fixed shaft, a shaping roll at the forward end of thefront 'section of shaft, fluid operated means for raising and loweringthe front section of shaft,fan'd an adjustable'table arranged below the 'shaping rolls and in operative relation thereto.'-

the combination with a shaft having a shaping roll atthe forward end thereof and a gear adjacent the rear end thereof, of a second shaft composed of a front and rear section connected together bv a universal joint,

a shaping roll from the forward end of the front section, a'gear upon" the rear section ,meshing with the gear upon the first named 'heath the shaping rolls and in operative relation thereto. f

In testimony whereof, we hereunto aix our signatures. I f FRED R. KLAUS.
